What household products would dye hair?

If you intend to dye your hair, use a proper hair dye, if you use anything else you run the risk of burning yourself or setting up a horrible skin reaction.

Although the above answer gives a good reason not to answer the question as intended.....it leaves out that u can use kool aid as a temp dye.....i have done it, i have red hair and i hated it so i dyed it purple using equal parts of razzleberry and tropical punch UNSWEETENED NEVER DO SWEETENED kool aid.....i now have amazing purple hair :)

You can also grab a Crayola washable marker, hair spray/gel, curling iron/hair straightener. No matter how bad this sounds, the trick is to burn it into the hair (or else it will fade). I tired it. Your hair feels stiff, but it looks REALLY cool and it works for any color you want. Just make sure it is washable...
